Install the Foundation How to Build a Shed The foundation gonna start by building the outside perimeter of the floor frame 0:04will move that frame into position 0:07locate exactly where we want the shed squared up once we establish where to 0:11dig the holes would move the frame model the way and start digging will fully 0:16explain how to build the floor system in the next chapter but for now all we need 0:20are two by eight cut to length and width of the shed you can get this link from 0:24your plan laid the perimeter Joyce are on the ground then they'll them together 0:29with 12 Dior 16 D galvanized fasteners were singer's 0:34other use the box to position your shed exactly where you want it relation to 0:39the house and the yard cross measure to roughly square the box and place the 0:45concrete blocks in the corners to establish places to remove the grass 0:48before the box I check for level from corner to corner this gives me a rough 1:00idea of how deep to dig for each block it's pretty obvious by looking at the 1:05highest part of the of the ground here but we use the level of check to make 1:09sure that that's where we're going to start from you don't want to start from 1:12the low part of the ground and try to work your way up because you'll find 1:16yourself digging very far down so we work from the highest spot in Doral Ale 1:20from the highest spot down to the lower spot that way toward easier to add 1:24blocked and it is to dig out or set the floor joists box aside and start digging 1:31I like to use a helper with the shovel to do most of the digging we're just 1:38going down below the topsoil topsoil is only 45 inches that's all we're going to 1:45go the soil beneath the topsoil here's gravel and water troubles right through 1:50it very easily so it doesn't do justice retain water retain water and it froze 1:55then it expands quite a bit but seeing that it's a lot of gravel the water goes 2:00right through it now you can either put a bunch of block there and build it up 2:05from there but I find it a little easier to grade it 2:08using stone left and right back and forth when we put the frame back on to 2:25position it right where it needs to go if the bottom of the block is above 2:31grave had enough crush zone around the edges to prevent the block from shifting 2:35over time 2:36any size crushed on homework to support the blocks as long as it swelled raining 2:40here I'm using a three-quarter inch size right now we're just gonna get a rough 2:45level again we're starting with this side on the right that's the highest 2:50point just putting a huge straight edge from one to the next level list up a 2:58little bit just put your weight ya star playa a little bit 3:04work around the perimeter from the highest block taking the time to ensure 3:09level foundation saves the headache down the road trying to straighten things up 3:13measure that and were either gonna add more stone or we drop that down and put 3:19a second second one on there so we just pull little stone out a second walk 3:26there 3:39box on the blocks square to make any final adjustments you need let's not try 3:47to move the back door locks in place until we plywood it right and we can 3:52move it around that way it will stay for the whole thing is going to shuffle 4:06faces flush with the floor
